To all whom it may concern Be it known that l, Anonrrr SCHNEIDER, a citizen the United States, residing at Chicago, in the county of Cool; and State of Illinois, have invented certain new and useful Improvements in Bottle-Filling Machines, of which the following is a specification.

The present invention relates to that type of mechanism used for the purpose of pack- 'ing carbonated liquids, or analogous substances, under pressure.

The objects of the present invention are, to provide a stationary support upon which the to-be filled packages rest during the filling operation; to provide a series of pistons, one of which will actuate the filling tube of the bottle filling mechanism, and the other or. which will actuate the sealing head; to provide a series of cylinders for said pistons, one piston being contained in each cylincer; to arrange system of pressure supply ducts for conveying pressure to said cylinders for the purpose of actuating the pistons; to arrange a series of ducts for eX hausting the pressure from the said cylinto so arrange these ducts, if desired, as to enable them to perform double functions, namely, that of an inlet and an eX- haust duct; to provide an automatically oper-ted valve for controlling the fiow of -iquid from the source of liquid supply to the filling tube, and in arranging this valve so that it is automatically operated at a time approxniately when the filling tube has reached its lowermost position; to provide a method of establishing communication between a source of air pressure less than the sure of the liquid in the tank and the i iior of the bottle; to provide a valve for controlling the flow of said air whereby said valve will be automatically operated to esta lish said air communication at practically the same time that the communication is established to permit the flow of liquid from the filling tube into the bottle; to proiide an arrangement whereby one of the sei of pistons may be power driven in both csections, and the other of said pistons n 1 be power driven in one direction only, bib last mentioned piston being moved in the opposite direction by contact with the first mentioned piston; and to provide a telescopic connection between the source of liquid supply and the filling tube, and a telescopic connection between the source of air supply and the sealing head.

Further objects or" the invention lie in the compactness of the machine produced by the arran ement ofthe cylinders and pistons for operating the filling tube and sealing head, and in the utilization of the crosshead connection between the filling tube and the piston operating as a means for establishing connection between the telescopic duct and the filling tube, and providing a continuous passage from the source of liquid supply to the filling tube.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

The present invention relates to that type of l1quid packaging machines in which the to-be filled package remains in fixed position, and the iilling mechanism is operated operative engagement to be brought into. with said package. The machine s designed so that it may, if desired, be used in conjunc -tion' with the counter-pressure system clescribed and illustrated 1n Patent No. 991,093, issued to nieMay 2, 1911, although, 01

course, theuse of this system is not essential to the carrying out of the present invention. 1n bottle falling machines, there areusu ally a plurality of these filling mechanisms centrally located tank, but as all" of the mechanisms alike and as all of them opcrate-in exactly the same manner, only one 1 cylinder-1 1, and a lower cylinderslf). These cylinders are arranged end to end, and may be classified as tandemly arranged cylinders.

Mounted-within the cylinder 11 is a piston 16, and within the cylinder 15 is a piston 17. Adjacent the lower end of the cylinder 15 is an air'hole15 to prevent an air cushion being formed below the piston 15 and pre{ venting its descent. The piston 16 has extending therefrom an upwardly extending piston rod 18 which is joined to a cross-head 19 which in turn is connected to a filling tube 20. The piston 17 has secured thereto a stem orsleeve 21 which is connected to a pipe 22 through'the medium of a suitable coupling As shown more clearly in Fig. 6, the piston 16 has attached thereto a piston rod 21 which extends in the opposite direction from the piston rod 18, said rod 24 passing through the cross-wall 13 and extending into the hollow interior of the sleeve 21. A series of pins or lugs 2% are attached to the piston, which act as stop members to limit the movements of said piston.

A. suitable packing 25 is employed where thero'd 2-1 passesthrough the wall 13 so that there is no danger of a passage of pressure between the interior of the upper and lower cylinders. The rod 2 1 terminates in an en;- largement 26 which is designed to engage the piston 17, said engagement being brought about in the form shown by providing an inwardly extending flange 27 on the sleeve 21 with which said enlargement engages,

arranged around a and'as will be seen from a study of Fig. 5,

'this'sl'eeve is screw-threaded onto the piston- .1'1; and hence when the engagement is efpressure, preferably compressed air," and means have to be necessarily provided for the conduction of this pressure to the cylinders,and for the eduction therefrom;

he mechanism which 1 have illustrated to ca ry out this portion of my invention is i as follows: The lower cylinder l'tg has-seg cured to its lower end a cap 28, and said cap is formed with a lug or projection 29 in which is mounted a rotatable tapered valve 30'. Said valve is better illustrated in Figs. 5, (5, and 11, and consists of four passages,- 5 81, 52, 33, and 34. Each of these passages, as shown, are of arcuate formation, and have their open ends extendingat approximately right anglesto one another. The-passages 31- and 32 are for the purpose ofcontrolling the supply of compressed air or other me dium which is designed to enter a series, of pipes 35 and ltach of these pipes'has one end thereof secured into a lug 87 fixedly secured adjacent the cross-wall 13.. As will be seen from a study of Fig. 6, the adjacent ends of the pipes are spaced away. from one another, and a chamber 38 is formed in the interior of the lug 37 which lies intermediate the adjacent end of these ice pipes. Leading from this chamber 38 is a by-pass v59, also best shown in Fig. 6, which communicates with the interior of the cylinder 15' at the upper end thereof. The'pipe 36 has its'upper end entered into" a lug 4E0 secured to a cap piece 11 which is positioned to the upper end of the cylinder 14, and formed in this lug is a passageway e2 com inunicating with the upper end of the pipe 36 and the interior of the cylinder 1 111 the upper end thereof. w

T he ports 33 and 31 of the valve 30 com municate with a pipe 13 which has its lower end secured to the collar 28, and its upper end secured within the lug 37, and formed in said lug is a passageway 11 which commit nicates with the upper end of the pipe 13 and with the interior of the cylinder ll at the lower end of said cylinder.

The 'operationof this valvular controlled mechanism is as follows: With the ports of the valve shown in the position indicated by the full lines in Figs. 5 and 6, the port 31 is in communication with the main pressure supply passage 1-5 which leads from a suit able nipple 16, best shown in Figs. 10 and 11, to which may be joined a conduction member for the main source of pressure 7 supply. Said port 31 is also in communication with a passage 47 in the lug 29, so that the pres- 3 sure medium entering through the passage 15 will flow through the valve passage 3%, the passage all, the pipe '13, the passage and into the lower one of the cylinder 14:, and the passage 33 will be out of communication with said pipe. ll hen the valve is turned to bring the passages 33 and into this position, which is the position they assume when pressure 1 icing admitted to s l raise the p1'".ll the port will be in communication with a passage '17 in the lu 29 and with anexhaust no that the into the pipe medium above the piston 1 out through the bypass 39 and out through the exhaust po t 18, and th medium above the piston 16 will be passing through the passageway 12, ip 36, chai ber 38, pipe 35, and

e out through the exhaust port; thus, with the valve in the position shown by the full lines in Figs. 5 and 6, pressure is being exhausts 1 from above the pistons 16 and 17 and is being admitted below tile piston 16.

It will be noted at this point that there is no arrangement provided for admitting pressure below the piston 17. This is because of the fact that in the arrangement shown, the piston 15 is drawn upwardly by the engagement of the enlarged head with the flange 27 or" the slee e so that no positive pressure means is needcc which will act directly upon this piston for the purpose of raising it. When the valve is turned, so as to bring the ports into the position shown by the dotted lines in Figs. 5 and 6, pressure will be exhausted i m beneath the piston 16,

ill be admitted and at we the tons 16 and 17. Thereiore, upon each. quai ter turn f said valve, pressure is supplied to the interior of the cylinders to move the piston in an opposite direction to that which they had been moving.

it will be noted that with the valve in one position, the pipe i3 is an induction pipe, and when the valve is turned a quarter revolution said pipe becomes an eduction pipe, and it will also be noted that with the valve in one position, the pipes and 36 are induction pipes, and when said valve is given a quarter revolution said pipes become educ tion pipes. 1, therefore, employ but two sets of pipes, and means of the valvular control, 1 am enabled to utilize these pipes both for induction and eduction purposes, they alternately performing one func ion and then the other.

The means which 1 e1 iploy for conducting the liquid from the source of liquid supply to the filling tube is perhaps best illustrated in Figs. 1 and 7, and consis in a pipe 49 which is in communication with a nipple 50 leading from suitable source of liquid sup ply. Telescoping within this pipe 49 is pipe 51 which passes through a bushing in the cap piece The pipe 51 is entered i be p sing into the cross-head 19, and communicates with a passage 53 therein leading to a chamber 5 1 also formed in said cross-head. EX- tending from the chamber and in the op posite direction from the passage 53 is a passage 55, and at the juncture oi the passage with the chamber 54: is a suitable shiftable valve 56 formed with a stem 57, and normally held in seated position by the action a coil spring 58, and the passage 55 communicates with the filling tube 20.

From a study of Fig. 7, it will be seen that there is a continuous passage extending between the nipple 50 and the filling tube 20 and that the flow of liquid through said passage is controlled by the movements of the valve It will be further noted that although this passage betw en the source of liquid supply and the filling tube is continuous, it is capable of being made longer or shorter by reason of the telescopic arrangement of the tube 51 with the tube This is, of course, essential; that is, it is essential to have some connection which is capable of moving with the cross-head, and such movability is made necessary because of the fact that the cross-head 19 and the filling tube 20 are both connected to the piston rod 18, and said piston rod travels up and down in con tormity to the movement of the piston, which movement raises and lowers the filling tube into proper position with r pect to the interior oi the to-be filled package.

The valve 56 is provided for the purpose of providing some means for admitting liquid to the filling tube only at a. time when said filling tube is in proper position with respect to the interior of the to-be filled package. By the arrangement shown, the valve is made automatic in its action, and the time of its action is made certain so that iu may only act when the filling tube is in proper position within the to-be filled package. As the piston 16 travels downwardly carrying witi it the piston rod 18 and the cross-h ed 19, the valve stem 57 will descend until it strikes the upper face of the cap 11 or some other suitable contact. When this contact is effected, the valve will be pushed upward unseating it from the end of the passage and liquid can then pass through said passage into the interior of the filling tube and to the interior of the to-be filled package. it is obvious that if this contact located in proper position, there can be no actuation ot the valve save when the filling tube is in proper position with respect to the interior of the to-be filled package,- so there is no danger of an cscapement of liquid before the filling tube has reached this proper position, nor is there any danger of an escapement during the raising and lowering of said tube. The timing of the movements to properly control the raising and lowering of the filling tube is brought about by an arrangement of a series of-contacts, not shown, which engage and rotate a star wheel 59 that is connected to the valve 30.

As heretofore stated, the piston 17 controls the movements of the sealing head which is designated by the numeral 60.

r This sealing head is shown more in detail in Fig. 7, and consists of a flaring outer sec tion 61 secured in a lug or extension62 on a sliding cross-head 63. The sealing head is provided on; its interior with a suitable seat 64, preferably formed of compressible.

material which engages the upper end of the neck of the bottle or to-be filled package, and, as shown, the interior of the'sealing head is formed with a passageway 65 through which fthe filling tube '20 extends. This passageway communicates w th a passage 66 leading toa chamber 67 in which is located a suitable check valve 68 for the purpose of preventing a passing of the overflowing liquid therethrough, and leading from the chamber 67 is a passage 69 extending in opposite directions from the passage 66 and communicating with a chamber 70 which communicates with the. upper end of the pipe or tube 22.

Lying in the interior of'the pipe 22 is a tube or pipe 71, which, as shown more clearly in Fig. 7, is of a reduced diameter from the interior bore of the pipe 22, so that a clearance or passageway 7 2 is provided between said pipes. The pipe 71 extends downwardly a suitable distance into the pipeQ, and hasits lower end open. The

' end of the-pipe 2:2 may, if desired, have secured theretoa suitable pet-cock 73 which isfor the purposeof enabling any sediment which may collect in the pipes22 and 71 to be cleared out therefrom. This pet-cock not be employed unless it is deemed-ex pedient by the mechanic constructing the machine. Y Y

The pipe '71 is secured to a coupling member 74 which is secured with a suitable packedconnection 75 to a lug 7 6 extending from or secured to the cap piece 41. This lug 7 6 has formed therein a chamber 77, and

located in said chamber is a Slidable valve dered'necessary in order that it may avoidcommunication with the interior of the cylinder 1% which, as will be seen from the drawings, is projecting "thereinto. This passageway is for the purpose of conducting the air which is under a'pressure slightly less than the pressure upon the liquid in the tank, such pressure being maintained in the l manner shown and described in Letters Pat ent No. 991,O93,'issued to me'May 2, 1911, This principle briefly is to maintain a body of air within a chamber which will have pressure slightly less than atmospheric, so that as the air is driven from theinterior of the to-be filled package by the incomingliquid, it will be displaced against the counter pressure action of the air coming from the chamber.

a gradual displacement will take place, and

the'liquid will enter the bottle with a slow,

and easy movement preventing any foaming or violent agitation which is extremely undesirable. L a

By the telescopic arrangement of the pipes 22 and 71, the-interior of said pipes will be in constant communication, although the pipe 71 remains fixed with respect to the movementofthe sealing head, and; the pipe 22 moves with said sealing head. The sealing head is raised or lowered by the action of the piston 1?. It might be noted at this point that by referring to Fig. 3, it will be seen that the cylinder 15 isshorter than the cylinder 14-. Thisis because ofthe fact that the piston 16 which raises and lowers the filling tube has a longer distance to travel thanthe p1ston117 whi'chraises and lowers the filling head. The filling head is brought to a stop by its engagement with the neck of the bottle, or to-be filled pack- I This naturally checks the movement of the out'fio-wing air so that I age, while the filling tube co'ntinues to descend until it reaches a point. close to the age; and hencethereis a difference in the rest first, and tliQCI'OSS-llGfi-d 19 which carries the filling tube will continue to descend until it is arrested by some suitable stop member. When it has reached approximately its limit of descent, thecross-head 19 will engage the head 81 ofthe stem ofthe valve 78 and force said valve away from its seat 79. T he movement of the valve, however, will not be sufficient so that it will close communication between the upper end of the pipe and the chamber 77,. and air pressure will flow from said'chamber into the pipe 71, into the space 72, into the cham ber 70, through the passage 69, into the chamber 67, through the passage 66, into the open end of the sealing head, and thence into the interior of the bottle. This is the course'described for the, air which has heretofore been referred to as being of pressure ,lower end of the bottle, or'to be filled packslightly less than the pressure on theliquid i so 'ibcd By head 19 for the purpose 7 increments of the valve e seen that said valve n and communication movement, and this is device which is deemed oeration. The support is in the form of suitable 1r .nner. and shown, is formed integral with the cross-wail This shoe, it is undei ,tood, remains in fixed position so that no movement of the bottle with respect to the filling apparatus is allowed.

The cpei tion of the device will be underthe foregoing, but brieliy is as ith the ports the valve arhe position shown by the dotted and pressure will be adl6 and above the of these pistons piston down -i i espective cylin ders.

Themovementof the pistons upwardly is arrested by suitable stop upon the pistons themselves, or in any other suitable manner.
